Abstract: A dispute is provided in  the paper over that Marxist views of that art is a means to observe the world,a social ideology and a production.And alsoa doubt is put forth for the three propositions that neo-aestheticism takes art as materialization of an artist's aesthetic conception;art is the comprehensive presence or expressing form of beauty;art sees beauty as its goal.In addition a general discussion is given for the conception of considering art as a form of life.The conclusion holds that it's hard to give a good definition of art.

Key words: art, Marxist, neo-aestheticist
